Make ShareThis Button Float

Hello I am using a share this button on my website and would like to make it float vertically as the user moves up and down the content in a page. We have a html site with a Dreweaver template that is connected to all the pages.

Currently the Share this button is on top of the page under the the main header image(banner) and above the drop-down menu ( main negation ) So it is appearing as if it is in a table ( within a cell) and we have an entire section ( cell ) that is showing up as black and is acting as a divider that which we don't want to see.
Here is a link to share this button website. I see it floating on their site. :-)

Jason,
Here is the adobe Dreamveaver file that we are using. I have saved it as an HTML file. I hope it helps.
The reason that I wanted it to float vertically was to get rid of the long cell that appears above the css drop-down menu. If you could help me somehow get rid of that cell, I could do without the shareThis buttons floating. Ideally, I would like to have the Sharthis button, to appear at button right hand corner of the top banner. So the Sharthis button would be in the front of the Head-fin.gif image and on its righ hand bottom corner. This would be as if it was setting on top of the drop-down menu on the right side.
I have also attached a css file for the drop-down menu just in case you want to see it.

Now the icons should float. You can change the values of left and top in order to position it correctly. For instance, you can use left: 1000px and top: 125px to return it back to where it was originally.
